Due to popular demand and Justin deleting the original post, here we go again.
I upgraded the stock binding posts on my SDA SRS 2.3TL's to Cardas gold plated posts, the short length type. Here is the info as best as I can remember it.
First remove the binding post plates from the back, there are four screws. The wires are connected to the crossover by a quick connect, just reach up inside and disconnect. There is a hot glue type material on the back of the plate that must be removed, I did this by gently prying up from the edges. You will note that each wire has a color band on it, make a drawing of what goes where for reference. Remove the wires by unscrewing the nuts and then remove the posts. The Cardas posts are larger than the stock ones and they have a shoulder. I placed the new posts over the old holes and marked a outline of the new posts. I then used a Dremel tool to enlarge the hole, being very careful not to round out the hole. IMPORTANT: You must leave the sides flat for the shoulders on the new posts. I used a fine small half round file on the flat sides and the curved area to get the right shape and size. The following pics are of the front and back of the stock units.
